The invention relates to a linseed cake discharger for removing thelayers of pressed meal from the cage in which the meal is pressed. Theinvention has for its principal objects the provision of improved meanswhich will automatically remove the layers of meal from the cage, asthey are pushed upward through the cage by the press ram-or plunger, andwhich is so constructed that the tearing of the cloth sheets whichseparates the layers of meal is avoided. One embodiment of the inventionis illustrated in the accompanying drawings, wherein:

Figure 1 is a front elevation of the apparatus. Fig. 2 isa sideelevation. And Figs. 3 and 4 are enlarged detail views of theconstruction of the stripping wheels and their relation to'the series ofmeal cakes or layers.

Referring to the drawings, 1 is the pitin which the lower portion of theapparatus is mounted, and 2, 2 are a pair of beams, which take theweight of the frame and theparts carried thereby. The frame comprisesthe pair of castings 3 and 4 connected by the four guide 7 extendsthrough the press table 8 guided rods or posts 5. Supported by the lowereasting is the hydraulic cylinder 6, whose plunger for vertical movementon the posts 5. The press table is supported from the casting 3 by meansof a pair of jacks 9, such table being provided with a drip pan 10having a pipe 11 leading to the drain 12.

Supported upon the table 8 is a cage 13 carrying the meal cakes orlayers 14, fr0m which the oil has been pressed and which must now beremoved. These layers are separated by the layers of cloth or felt 15and are tightly adherent to each other due to the high pressure employedin pressing out the.

oil. The cage comprises a steel shell of rectangular form open at bothends and when in position on the table 8 is supported against upwardmovement by the stops 1'6 resting against the lower side of the casting4 and secured to the guide posts 5. The cages are brought to position atthe side of the apparatus on trucks 17 whose tops lie at the level ofthe top of the table 8, so that the, cages maybe easily slid onto thetable and removed therefrom.

'ries of cakes or layers in the cage is removed,

Extending transversely of the frame atone I side thereof (Fig-,2) is ashaft 18 supported in bearings 19,v 19 carried by the posts5, such shaftbeing driven from the line shaft 20 through the intermediaryv oft-hespur wheel 21,the 'pinion 22 (Fig. 2) on the countershaft 23, the pulley24 on the shaft 23 and thebelt 25' passing around the pulley 24 and thepulr ley 26 on the line shaft 20. Keyed to the shaft 18 is a pair ofstripping wheels, each comprising a pair of sheet metal discs 27, 27(Figs. 3 and 4) between which are mounted the series of strippingmembers or teeth 28, 28, etc. The discs are provided with the hubmembers 29, 29 keyed to the shaft 18. The members 28 are pivoted on thepins30, 30, etc. carried by the discs 27, 27 v and heldagainst backwardmovement beyond a certain point by the stop pins31, 31, etc. alsocarriedby the discs. e

The timing of the upward movement'of the plunger 7 and the'rotationof'the shaft i 18 is suchfthat, as eachlayer or cake 14 rises above thetop of the cage 13, its edge is engag-ed by one of the members 28, asindicated in Fig. .4, and such edge is 1ifted,thus loosening the cake sothat the further movementof the stripping wheel pushesiit to the left.This operation continues until the entire seat which time the cage isremoved onto a waiting truck and another'cage is placed in position onthe table 8. Further, the timing of I cakes and their cloth layersbefore the pins 31 engage the'ba'cks of the members, so that in eachcase an impact efiect is secured when the pin strikes themember (alreadyinengagement with the edge of the cake) thus giving a better looseningaction than if the members 28 were rigid withrespect to the wheel 1carrying them. The apparatus 'reolucesthe' '90 The members swing d0wnto'ver .tical position and engage the edges of the hand labor incidentto freeing the meal cakes from the cage and from each other, andinvolves a large saving in time.

What I clalm 1s: 7 In combination in apparatus for dlscharging mealcakes from the cage in which they are pressed, means :for removingthe--1ayers of meal as they emerge from the cage comev prising a heelmounted above the cage at one side thereof, 'a plura'lity "of jpiVdtedteeth' carried upon thewheel at'equally spacedintervals, stops on theWheel fonlim-iting the movement'of the teeth to the rear, and meansfor'rotating the wheehsaid wheeLbei-ngipositioned so that its teethengage the edges of saideakes andseparate them fro'm th'e body of -1nealcakes in "the cage therebenea'th;

In testimony whereof, I have hereun'to ilbi scribed "my name this 7 dayo'f January, 1929.
